golang微服务项目通用流水线

工作中随着业务越来越大，微服务的项目也越来越多，最开始的时候是一个服务一个流水线，然后还分了三个环境，也就是一个服务三个流水线，后面就越来越不利于管理维护了，因此，进行了一个改造整合

golang这边的微服务基本分成三类，service、schedule、mq，所以将所有流水线整合为三条通用流水线，再通过参数传递的形式，去构建每个服务

一、dockerfile和jenkinsfile

这是service里面的dockerfile和jenkinsfile，schedule、mq大同小异

dockerfile

FROM ccr.ccs.tencentyun.com/chens/golang:1.17.13
ENV ZBE_PATH /biz-code
ARG SERVICENAME=message
COPY $SERVICENAME /biz-code/$SERVICENAME
WORKDIR /biz-code
RUN chmod 777 $(echo `ls -l` |awk -F ' ' '{print $NF}')
USER root
RUN ls -l
CMD ./$(echo `ls -l` |awk -F ' ' '{print $NF}')
